Sigma Spectrum Recalls and Software Versions: FDA Notices for V6 and V8 Pumps

The Sigma Spectrum has a long FDA record. Some notices involve software and are fixed by an update or reversion; others involve hardware, labeling or pumps released from service without full testing. This guide puts the V6 and V8 notices in one place, in plain English, so your team can tell which pumps are affected and what to do next.

Who Makes the Sigma Spectrum

The Spectrum was developed by SIGMA International General Medical Apparatus, LLC of Medina, New York, which is why older pumps, manuals and recall notices carry the SIGMA name. In 2009, Baxter signed an exclusive global distribution agreement with SIGMA and took a 40 percent equity stake with an option to buy the rest. Baxter exercised that option and completed the purchase in April 2012. Baxter Healthcare Corporation is the current manufacturer and the recalling firm on recent notices. Spectrum IQ, with Dose IQ Safety Software, is a separate Baxter pump; several notices below also covered it, but this guide covers only the V6 and V8 parts of them.

Sigma Spectrum Software Versions

V6 and V8 pumps look alike, and the software version is what tells you which notices apply. These are the versions named in the manual we host and in FDA records:

FDA records show some 35700BAX pumps on pre-6 software such as 5.02.06, and the manual mentions 4.02.06; the “begins with 6 or 8” check in Baxter’s 2025 notice is for V6 and V8 software. Baxter has not published a current-version list that we could verify, and the 2020 correction for a programming error (Z-0712-2021 to Z-0714-2021) does not name versions. Confirm the current release for your fleet with Baxter, and contact us if you want help reading what your pumps show.

How to Check Your Sigma Spectrum Software Version

1. Turn the pump on and note the software version on the start-up screen.
2. On a V6, you can also open the Pump Information screen and press the sw info soft key, which lists the Sharp, PIC, CPLD, charger and network module versions too. On a V8, from the Select Care Area screen press the options menu soft key, then select User Options, View Information and Pump Information (press OK after each) to open the Pump Info screen.
3. Confirm the version matches the platform: V6 software begins with 6 and V8 software begins with 8. V6 pumps typically carry product code 35700BAX or 35700ABB (FDA records also list variants such as 35700BAXR), and V8 pumps 35700BAX2. The software version is the deciding check.
4. Record the version and serial number for each pump in your asset system so you can act quickly on future notices.

Sigma Spectrum Class I Recalls

Class I is FDA’s most serious recall classification. Eight Class I events have involved Sigma Spectrum V6 or V8 pumps:

The 2020 cleaning correction and the 2021 V8 upstream occlusion notice remain the most relevant to daily practice, because they applied to all serial numbers and depend on how pumps are cleaned and how alarms are handled. The 2025 notices apply only to listed serial numbers, but checking that every pump’s software matches its platform takes seconds.

Class II and III Recalls and Corrections

These Class II events involved V6 or V8 pumps, their software, their batteries or their accessories:

One Class III event also applies: in April 2012, SIGMA issued a customer safety alert for all versions of the Master Drug Library (MDL) Editor software, because it could produce a facility drug library that does not reflect common clinical practice (Z-2030-2012).

Many of these surface at the bedside as upstream occlusion alarms, system errors or battery problems. Our Sigma Spectrum common problems guide covers what we find when those pumps reach our lab.

What to Do Now: A Checklist for Biomed and HTM Teams

1. Record the software version, product code and serial number of every Spectrum, and confirm V6 software begins with 6 and V8 with 8.
2. Check your serial numbers against the listed-serial notices, especially Z-1253-2025, Z-2095-2025, Z-2096-2025 and Z-1121-2026.
3. Inspect rear case pins and battery contacts for residue or corrosion at every PM, and confirm your cleaning agents and methods match Baxter’s current instructions.
4. Make sure V8 users know not to press RUN/STOP until an upstream occlusion has been found and cleared.
5. For V8 pumps on v8.01.01, confirm the reversion has been completed.
6. Store spare batteries as Baxter advised in 2021: out of the pump, at 2 or 3 bars of charge, between 14 and 95 °F, recharged every six months.
7. Run annual PM with flow-rate accuracy, air-in-line and occlusion checks on every pump.
8. Check Baxter’s notices and FDA’s recall database for anything newer than this guide.

Sigma Spectrum Recall FAQ

Is the Sigma Spectrum recalled?

Sigma Spectrum V6 and V8 pumps have been the subject of many FDA recalls and corrections since 2010, eight of them Class I. Most were corrections, such as updated instructions, software changes or service for listed serial numbers, rather than removal of every pump. The most recent Class I recall, from June 2025, covers specific serial numbers that may have the wrong software installed.

What was the Sigma Spectrum software mismatch recall?

In June 2025, Baxter recalled 14 listed V6 and 28 listed V8 pumps (Z-2095-2025 and Z-2096-2025) that may have the other platform’s software installed. Users were told to remove those pumps from service, check that V6 software begins with 6 and V8 software begins with 8, and contact Baxter.

What was the Sigma Spectrum battery corrosion recall?

In 2020, Baxter issued a Class I correction (Z-0120-2021 to Z-0122-2021) because improper cleaning can leave residue or corrosion on the rear case pins and battery contacts, which could cause a pump on battery power to shut down without an alarm. Baxter updated the instructions for use and asked facilities to inspect the pins and contacts on all pumps.

What should V8 users do about upstream occlusion alarms?

Baxter’s December 2021 Class I notice (Z-0530-2022) says not to press RUN/STOP before inspecting the tubing and resolving the occlusion, because the pump could appear to infuse while delivering less or nothing. In 2023, Baxter also began reverting V8 pumps on v8.01.01 because of false upstream occlusion alarms.

How do I check the software version on a Sigma Spectrum?

Turn the pump on and read the version on the start-up screen. On a V6, the Pump Information screen’s sw info soft key also shows it; on a V8, from the Select Care Area screen press the options menu soft key, then select User Options, View Information and Pump Information (press OK after each) to open the Pump Info screen.

Who makes the Sigma Spectrum now?

Baxter. The pump was developed by SIGMA International of Medina, New York. Baxter signed a distribution agreement and took a 40 percent stake in 2009, then bought the remaining 60 percent in April 2012.

Can IPR Medical check my pumps against the recalls?

Yes. We can check software versions against the published notices and evaluate pumps for the hardware issues they describe. Recall remedies such as software reversions and returns for reservicing are provided by Baxter, so for any pump on a recall list, contact Baxter as its notice directs; Baxter’s notice lists the affected serial numbers. Contact us about your fleet.
